Sorry, I couldn't really see anything in that video, but, our cars are equipped with "smart" cruise control when equipped with the DCT. Basically the car will use the transmission to downshift momentarily to maintain the set speed exactly, this prevents the car from coasting and gaining extra speed. It talks about it in the manual....I like to hypermile, so I don't use cruise control on hilly areas on the highway because of that. Even very slight inclines can get annoying.
